Book excerpt: How big should a corporation be? Is there a limit to their size? Should corporations be regulated to serve the public interest? What are the dangers of monopoly? Should monopoly be restrained? Henry Ford, one of America's greatest business innovators, explored these concepts and others in this 1926 tome of business philosophy, and his discussions are still fresh, vital, and applicable today. Considered "insane" for the very innovations we hail as visionary today-the assembly line, reduced working hours, a minimum wage, the five-day work week-Ford's instruction is well worth examining by those looking to understand the American economy past and present. ALSO AVAILABLE FROM COSIMO CLASSICS: Ford's autobiography, My Life & Work. American entrepreneur, inventor, and philanthropist HENRY FORD (1863-1947) was born in Michigan and trained as a machinist and engineer before founding, in 1903, the Ford Motor Company.
